Privacy Policy

• Account information — your name and email address, handled through our authentication provider, Clerk.
• Payment information — when you subscribe, payments are processed by Stripe. We do not collect or store your full card details; we receive limited billing status (such as active or cancelled, and renewal date) to manage your membership.
• Content you save — the lessons you bookmark.
• Usage data — which pages and features of the Service you use, such as reaching the checkout step, so we can see where people get stuck. It is recorded against your account identifier, not your name or email address, and we do not record your screen.
• Technical data — standard server logs (such as IP address, device and browser, and timestamps) needed to operate and secure the Service.

We do not show ads, and we do not sell your personal information.

To create and manage your account and membership, deliver and stream video content, provide support, keep the Service secure, and understand how the Service is used so we can improve it.

We rely on a small set of providers that process data on our behalf: Clerk (authentication), Stripe (payments), Bunny.net (video hosting and delivery), Vercel and Neon (application hosting and database), Sentry (error monitoring), and PostHog (usage analytics). We share only the data each provider needs to perform its service on our behalf, and we require each to protect it consistently with this policy. Their handling of data is also governed by their own privacy policies.

We use cookies and similar local storage to keep you signed in (via Clerk). These are necessary for the Service to function. We also use them for usage analytics (via PostHog), to tell one visit from the next.

We use reasonable safeguards to protect your information and rely on established providers, such as Clerk and Stripe, for authentication and payments. No method of transmission or storage is completely secure, and we cannot guarantee absolute security.

We keep your information while your account is active. You can delete your account and its data at any time from your account settings, or by emailing admin@kyokushinkan-technical.com — see how to delete your account. Usage data recorded against your account identifier is not removed automatically when you delete your account; we delete it on request. Some records may be retained where required by law or held by our payment processor.

The Service is intended for a general audience and is not directed to children under 13, and we do not knowingly collect personal information from children under 13. A parent or legal guardian is responsible for a minor’s use of the Service. If you believe a child under 13 has provided us personal information, contact us at admin@kyokushinkan-technical.com and we will delete it.

You can review and update your account information while signed in, cancel your membership at any time, and request deletion as described above. Depending on where you live, you may have additional rights over your personal information; contact us to exercise them.

We may update this Privacy Policy from time to time. We will post the updated version here with a new effective date.
